The transport, erosion and deposition of sediment are key elements for describing and understanding the behaviour of rivers and its planform changes. The expertise at IWM in sediment transport processes in rivers includes the full range of cohesive (muddy) as well as non-cohesive sediment from clay to silt, sand, gravel and boulders. While short term morphological changes now a days can be quite well studied by mathematical morphological models, the longterm changes to study requires combination of deterministic and stochastic approach due to the difficulty in long term hydrological and morphological boundary estimation. The services in this discipline encompasses the following:

• Fluvial hydraulics (water levels, flow patterns, discharge distributions, sediment transport)
• Morphological development of river network, River system, river beds and banks (lowland and mountainous areas)
• Impact of mine tailing, gravel and sand excavation, dredging spoil
• Siltation and maintenance of navigation channels and river ports
• Stabilisation of channels, river banks, off-takes, water intakes etc.
• Morphological consequences of engineering interventions.
